Rubber banding for GtkTreeView, #80127. Uses same method as GtkIconView.

Browse Source 
2006-06-02  Kristian Rietveld  <kris@imendio.com>

	Rubber banding for GtkTreeView, #80127.  Uses same method as
	GtkIconView.

	* gtk/gtktreeview.c (gtk_tree_view_class_init),
	(gtk_tree_view_init), (gtk_tree_view_get_property),
	(gtk_tree_view_set_property), (gtk_tree_view_set_rubber_banding),
	(gtk_tree_view_get_rubber_banding): add property,
	(gtk_tree_view_button_press): start rubber banding if enabled and
	press is on a non-selected node,
	(gtk_tree_view_button_release): stop rubber banding,
	(gtk_tree_view_motion_bin_window), (scrool_row_timeout): enable/update
	the rubber band,
	(gtk_tree_view_bin_expose): draw rubber band if active,
	(gtk_tree_view_stop_rubberband),
	(gtk_tree_view_update_rubber_band_selection_range),
	(gtk_tree_view_update_rubber_band_selection),
	(gtk_tree_view_update_rubber_band),
	(gtk_tree_view_paint_rubber_band): new functions.

	* gtk/gtktreeview.h: add new set/get function for rubber banding
	property.

	* gtk/gtktreeprivate.h: add a bunch of new private fields.
